All Known Implementing Classes:

AbstractListenerWebSocketSession, AbstractWebSocketSession, JettyWebSocketSession, NettyWebSocketSessionSupport, ReactorNettyWebSocketSession, StandardWebSocketSession, TomcatWebSocketSession, UndertowWebSocketSession

public interface WebSocketSession

Represents a WebSocket session.

Use session.receive() to compose on the inbound message stream, and session.send(publisher) to provide the outbound message stream.

HandshakeInfo getHandshakeInfo()

Return information from the handshake request.

bufferFactory

DataBufferFactory bufferFactory()

Return a DataBuffer Factory to create message payloads.

Returns:

the buffer factory for the session

getAttributes

java.util.Map<java.lang.String,java.lang.Object> getAttributes()

5.1

receive

reactor.core.publisher.Flux<WebSocketMessage> receive()

Provides access to the stream of inbound messages.

This stream receives a completion or error signal when the connection is closed. In a typical WebSocketHandler implementation this stream is composed into the overall processing flow, so that when the connection is closed, handling will end.

See the class-level doc of WebSocketHandler and the reference for more details and examples of how to handle the session.

send

reactor.core.publisher.Mono<java.lang.Void> send(org.reactivestreams.Publisher<WebSocketMessage> messages)

Give a source of outgoing messages, write the messages and return a Mono<Void> that completes when the source completes and writing is done.

See the class-level doc of WebSocketHandler and the reference for more details and examples of how to handle the session.

close

default reactor.core.publisher.Mono<java.lang.Void> close()

Close the WebSocket session with CloseStatus.NORMAL.

close

reactor.core.publisher.Mono<java.lang.Void> close(CloseStatus status)

Close the WebSocket session with the given status.

Parameters:

status - the close status

textMessage

WebSocketMessage textMessage(java.lang.String payload)

Factory method to create a text WebSocketMessage using the bufferFactory() for the session.

binaryMessage

WebSocketMessage binaryMessage(java.util.function.Function<DataBufferFactory,DataBuffer> payloadFactory)

Factory method to create a binary WebSocketMessage using the bufferFactory() for the session.

pingMessage

WebSocketMessage pingMessage(java.util.function.Function<DataBufferFactory,DataBuffer> payloadFactory)

Factory method to create a ping WebSocketMessage using the bufferFactory() for the session.

pongMessage

WebSocketMessage pongMessage(java.util.function.Function<DataBufferFactory,DataBuffer> payloadFactory)

Factory method to create a pong WebSocketMessage using the bufferFactory() for the session.
